# Updates
App updates are handled as an image update workflow, not as a live in-container
`git pull`.
The recommended sequence is:
1. Update the selected app branches.
2. Set a new `CUSTOM_TAG`.
3. Build the updated custom image.
4. Restart the stack.
5. Run `migrate` on the site if required by the app change.
The wizard keeps the current `frappe_branch` visible while you update apps so
you can see the base version the stack is built against.
`CUSTOM_TAG` is stored in the stack `.env` file. The Compose stack reads that
value on the next start or restart, so the tag change becomes effective once the
image has been rebuilt and the stack is restarted.
The update flow still rebuilds the image from a regenerated `apps.json`, and
`metadata.json` remains the source of truth for the stack state. The difference
is internal: stack metadata and generated app state are now processed through
`jq` instead of line-based `awk` parsing. No user-visible change in the file
layout is intended.
For now, this update flow focuses on app branch changes. A separate Frappe base
version update flow can be added later without changing the overall model.
